With regard to the Hirobo Astral - unfortunately, Hirobo products aren't very well distributed here in the United States. This could be a tough airframe to track down here in the States. Hirobo helicopter products will turn up occassionally. Your best chance would be to find a Hirobo helicopter dealer and ask them about special ordering the Astral.

With regard to spending $200+ for a .50-sized airframe - would you rather have the nicest flying .50-sized airframe on the market, or a mediocre .90-sized airframe for the same price?
